MACHINE FOR PREPARING WARPS FOR DYEING.

SPECIFICATION forming part of Letters Patent No. 242,987, dated June 14, 1881.

Application filed February 10,1881. (No model.)

To all whom it may concern:

Be it known that I, THOMAS RowLEY, of Lawrence, in the county of Essex and State of Massachusetts,have invented new and useful Improvements in Machines for Preparing Warps for Dyeing, of which the following is a specification.

The present mode of preparing cotton warps for dyeing is as follows: The warp is taken from, say six beams, run through starch and around a steam-cylinder to individualize, dry, and stiffen each thread; then it, is wound upon a beam; then the leases are picked by hand, and, finally, it is coiled and sent to be dyed.

By means of the machinebelow described, the starching, drying, pulling off the large beam, and the laborious hand lease-picking are dispensed with, and much time saved in Thus much time, labor, and money are saved.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure l is a plan view of the machine. Fig. 2 is a detached perspective view of the plain and block reeds and adjacent parts, with the thread in the act of forming the lease. Fig. 3 is a longitudinal vertical section of the-machine. Fig. 4 is a detached view of the taperin g roll L, the cam p, and adjacent parts, a portion. being in section. Fig. 5 is aview, partly in elevation and partly in section, of the taperin g roll L taken apart.

A is a frame supporting the beams B (two or three in number) carrying the warp. The bearings b b of the beams lie in supports or arms a in the frame. The beams B are provided with grooved flanges B, by means of which weights 1) are hung from ropes b in the grooves, the object being to keep the beams from turning too easily, and thus to keep the thread taut.

Swung, as shown in Fig. 3, from the rod 3, by means of a cord, 4, or similar device, and secured to the rod 1 by means of a cord, 2, or similar device, is the plain reed 0, between whose dents G the thread 00 from the upper beam and the thread 1 from the lower beam pass alternately, every other dent taking an upper, and every other a lower, thread.

The frame A supports the friction-rolls D and D, the threads from both beams passing over the former and under the latter, the blockvreed E, the friction-roll F, driving-roll Gr,aud

blocked, and are of the same number as the dents'O.

Slots 0 are provided in the blocked dents. The threads as from the upper beam pass through the slots 6 in the blocked dents, and the threads 3 from the lower beam pass between the plain den ts. Thence the threads pass over the friction-roll :F, around the actuatingroll G, and over the friction-roll H. The rolls Gr and Hhave their bearings in the verticallybifurcated portion H of the frame A, and the former is actuated by the wheel I, while the latter lies upon the former and is turned by friction.

The block-reed E is adapted to be raised and lowered by means, of cords d d passing around a shaft, d, which is operated by a crank, 61, all supported by the frame A, the object of such vertical movement being to form thelease, as below described.

From the roll H the warp passes through the eye K. supported by the rod J, which forms a part of the frame A. From the eye it passes to and is wound upon the tapering roll L, the construction of which is below described. This is a friction-roll having its bearings L in the bifurcated supports ff, extending up from the sliding frame or carriage g, which slides upon the shafts h h in order to reciprocate longitudinally the roll L, for the purpose of dis tributing the warp evenly upon it.

Splined to the shafts h h are the cloth or felt covered rolls k 70, which are arranged to rotate a little faster than the roll L, resting upon them, so that the roll L is constantly slipping, and hence winding the warp closely and solidly upon itself. The gear h It, which actuates the shafts h h, meshes into gear 1, (below and between them,) fixed to shaft Z, which is actuated by the wheel an, all supported by the frame A.

The follower nis fixed in the frame g and provided with the finger n, which is engaged by the cam 11, secured to the shaft 1. (See Fig. 4.) Thus the follower n and frame 9 reciprocate the roll L for the purpose of evenly distributin g the thread.

S is the driving-pulley, and is fixed to shaft T. The pulley S is belted to pulley m, which drives the mechanism upon the frame A, and

friction-roll H. The dents E are alternately the pulley U upon the shaft T is belted to the pulley 1, which rotates the roll G, and through its means draws the warp over or under the Various rolls and through the reeds from the beams B.

It will thus be seen that the warp leaves the beams B B, passes through the plain reed O, the upper threads, w, and the lower threads,

3 taking alternate dents over roll D, under roll D, through block-reed E, the upper thread, 00, passing through the blocks, and the under thread, 1 passing through the plain dents, thence over roll F, under and around roll G, over roll H, through the eye K, when it is wound upon the tapering roll L.

To take the lease, which is done once in, say, five hundred and twenty yards, lift the blockreed E by means of the crank d. By this means the upper threads,.r, which pass through the block-dents are raised, as in Fig. 2. Then pass a cord, 20, through the space between the two rows of thread. Then drop the reed E as far as it will go, by which means the upper threads, 01:, are pressed down by the said blockdents, return the other end of the cord through this space, raise the reed to the center, and the warp may be tied and cut off. The roll L with its contents may be removed and the warp taken off and sent to be dyed.

By examining Fig. 5 it will be seen that onehalf of the roll L may be slid off the central shaft, L, Which passes through it. To remove the warp, therefore, draw off the detachable portion and then it is easy to pull the warp ofi the remaining tapering portion and run a stick into the hole to keep the warp in shape.

A portion of the detachable part of the roll is made rectangular on the inside, so as to fit over a similarly-shaped part, L, of the shaft 'for the purpose of rotating the roll.

Thus it will be seen that the warp is run directly from the beams into a ball for dyeing purposes, instead of, as by the old method, taking it off the beams, starching and dyeing the warp, then putting it upon beams again and picking the lease, and then ceiling for the dye-house.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent, is-

The herein-described machine for preparing cotton-warps for dyeing, the same consisting of the frame A, adapted to support the beams B, and provided with the plain reed O G, the frame A, provided with the block-reed E E, the driving-roll G, and measuring-roll H, and the frame A, provided with the eye K, taperin g roll L, friction-rolls 7c k, and mechanism for evenly distributing the warp upon the roll L, all constructed and arranged substantially as and for the purpose set forth.
